What You Need To Know About Co-Signing A Mortgage

Danielle McIntosh • September 11, 2024

So you’re thinking about co-signing on a mortgage? Great, let’s talk about what that looks like. Although it’s nice to be in a position to help someone qualify for a mortgage, it’s not a decision that you should make lightly. Co-signing a mortgage could have a significant impact on your financial future. Here are some things to consider.


You’re fully responsible for the mortgage.


Regardless if you’re the principal borrower, co-borrower, or co-signor, if your name is on the mortgage, you are 100% responsible for the debt of the mortgage. Although the term co-signor makes it sound like you’re somehow removed from the actual mortgage, you have all the same legal obligations as everyone else on the mortgage. When you co-sign for a mortgage, you guarantee that the mortgage payments will be made, even if you aren’t the one making them.


So, if the primary applicant cannot make the payments for whatever reason, you’ll be expected to make them on their behalf. If payments aren’t made, and the mortgage goes into default, the lender will take legal action. This could negatively impact your credit score. So it’s an excellent idea to make sure you trust the primary applicant or have a way to monitor that payments are, in fact, being made so that you don’t end up in a bad financial situation.

 

You’re on the mortgage until they can qualify to remove you.


Once the initial mortgage term has been completed, you won’t be automatically removed from the mortgage. The primary applicant will have to make a new application in their own name and qualify for the mortgage on their own merit. If they don’t qualify, you’ll be kept on the mortgage for the next term.


So before co-signing, it’s a good idea to discuss how long you can expect your name will be on the mortgage. Having a clear and open conversation with the primary applicant and your independent mortgage professional will help outline expectations.


Co-signing a mortgage impacts your debt service ratio.


When you co-sign for a mortgage, all of the debt of the co-signed mortgage is counted in your debt service ratios. This means that if you’re looking to qualify for another mortgage in the future, you’ll have to include the payments of the co-signed mortgage in those calculations, even though you aren’t the one making the payments directly.


As this could significantly impact the amount you could borrow in the future, before you co-sign a mortgage, you’ll want to assess your financial future and decide if co-signing makes sense.


Co-signing a mortgage means helping someone get ahead.


While there are certainly things to consider when agreeing to co-sign on a mortgage application, chances are, by being a co-signor, you'll be helping someone you care for get ahead in life. The key to co-signing well is to outline expectations and over-communicate through the mortgage process.

The idea of owning a vacation home—your own cozy escape from everyday life—is a dream many Canadians share. Whether it’s a lakeside cabin, a ski chalet, or a beachside bungalow, a second property can add lifestyle value, rental income, and long-term wealth. But before you jump into vacation home ownership, it’s important to think through the details—both financial and practical. Start With Your 5- and 10-Year Plan Before you get swept away by the perfect view or your dream destination, take a step back and ask yourself: Will you use it enough to justify the cost? Are there other financial goals that take priority right now? What’s the opportunity cost of tying up your money in a second home? Owning a vacation home can be incredibly rewarding, but it should fit comfortably within your long-term financial goals—not compete with them. Financing a Vacation Property: What to Consider If you don’t plan to pay cash, then financing your vacation home will be your next major step. Mortgage rules for second properties are more complex than those for your primary residence, so here’s what to think about: 1. Do You Have Enough for a Down Payment? Depending on the type of property and how you plan to use it, down payment requirements typically range from 5% to 20%+ . Factors like whether the property is winterized, the purchase price, and its location all come into play. 2. Can You Afford the Additional Debt? Lenders will calculate your Gross Debt Service (GDS) and Total Debt Service (TDS) ratios to assess whether you can take on a second mortgage. GDS: Should not exceed 39% of your income TDS: Should not exceed 44% If you’re not sure how to calculate these, that’s where I can help! 3. Is the Property Mortgage-Eligible? Remote or non-winterized properties, or those located outside of Canada, may not qualify for traditional mortgage financing. In these cases, we may need to look at creative lending solutions . 4. Owner-Occupied or Investment Property? Whether you’ll live in the home occasionally, rent it out, or use it strictly as an investment affects what type of financing you’ll need and what your tax implications might be. Location, Location… Logistics Choosing the right vacation property is more than just finding a beautiful setting. Consider: Current and future development in the area Available municipal services (sewer, water, road maintenance) Transportation access – how easy is it to get to your vacation home in all seasons? Resale value and long-term potential Seasonal access or weather challenges What Happens When You’re Not There? Unless you plan to live there full-time, you'll need to consider: Will you rent it out for extra income? Will you hire a property manager or rely on family/friends? What’s required to maintain valid home insurance while it’s vacant? Planning ahead will protect your investment and give you peace of mind while you’re away. Not Sure Where to Start?

Buying your first home is a big deal. And while you may feel like you’re ready to take that step, here are 4 things that will prove it out. 1. You have at least 5% available for a downpayment. To buy your first home, you need to come up with at least 5% for a downpayment. From there, you’ll be expected to have roughly 1.5% of the purchase price set aside for closing costs. If you’ve saved your downpayment by accumulating your own funds, it means you have a positive cash flow which is a good thing. However, if you don’t quite have enough saved up on your own, but you have a family member who is willing to give you a gift to assist you, that works too. 2. You have established credit. Building a credit score takes some time. Before any lender considers you for mortgage financing, they want to see that you have an established history of repaying the money you’ve already borrowed. Typically two trade lines, for a period of two years, with a minimum amount of $2000, should work! Now, if you’ve had some credit issues in the past, it doesn’t mean you aren’t ready to be a homeowner. However, it might mean a little more planning is required! A co-signor can be considered here as well. 3. You have the income to make your mortgage payments. And then some. If you’re going to borrow money to buy a house, the lender wants to make sure that you have the ability to pay it back. Plus interest. The ideal situation is to have a permanent full-time position where you’re past probation. Now, if you rely on any inconsistent forms of income, having a two-year history is required. A good rule of thumb is to keep the costs of homeownership to under a third of your gross income, leaving you with two-thirds of your income to pay for your life. 4. You’ve discussed mortgage financing with a professional. Buying your first home can be quite a process. With all the information available online, it’s hard to know where to start. While you might feel ready, there are lots of steps to take; way more than can be outlined in a simple article like this one. So if you think you’re ready to buy your first home, the best place to start is with a preapproval! Let's discuss your financial situation, talk through your downpayment options, look at your credit score, assess your income and liabilities, and ultimately see what kind of mortgage you can qualify for to become a homeowner!
